In addition, when acidic water including minerals or poorly soluble salts and hydrogen ions react in the reactor, acidic water must contain abundant hydrogen ions to show excellent reactivity with minerals or poorly soluble salts, resulting in a strong reducing power and abundant minerals. Since the reduced water can be taken out, the water introduced into the reactor must be able to maintain acidic properties.

Acidic water is used to generate hydrogen ions through cation exchange resin.

Ion exchange resin is a cation such as of magnesium hydrogen cations (H ⁺ type), a cation exchange resin and water toxic anion for processing exchanged anion exchange resins to process exchange ^- the (OH ^- type ^- to Cl), OH ^- to Cl It is distinguished by.

However, when preparing the reduced water, it is necessary to remove the harmful anions, so that the cation exchange resin and the anion exchange resin pass through. When passing through the anion exchange resin, the pH of the water rises, which requires a certain level of acidity. There is a risk of losing.

Therefore, while removing harmful ions through the cation / anion exchange resin, there is a need for a new and advanced technology to ensure a certain level of acidic pH required in the reactor for the production of reduced water.

Another object of the present invention is to measure the pH of the water discharged from the reactor in order to control the acidity / alkalinity of the water passing through the reactor and when the pH is different from the standard pH, the prepared acidic water or alkaline water is treated around the reactor outlet.

A further object of the present invention is to precisely control the opening and closing degree of the check valve according to the PH information detected by the PH detection sensor by an automatic control method by the controller.

As can be seen from Figure 1, the ion-reduced water production method using the ion exchange resin according to the present invention, the cationic resin treatment step of basically reacting the water with the cation exchange resin, the water passed through the cation resin and the anion exchange resin and Anion resin treatment step for reaction treatment, first PH detection step for determining whether the water which has passed the above two steps has acid property, first PH control for acid treatment when water does not have acid property Step, adding water into the reactor to generate minerals and treating with reduced water at the same time, second PH sensing step to determine whether the water after mineral generation has a reference PH, water after mineral generation does not have a reference PH A second pH adjusting step of supplying acidic to basic water to adjust the pH of the water that has passed through the reaction water to a specific pH when the This is composed of a step of ejecting the reduced water.

The main hardware configuration of the method according to the invention is a cation exchange resin or an ion-regulated cation exchange resin filter, an anion exchange resin or anion-controlled anion exchange resin filter, a reactor supplied with various minerals and a first for PH measurement , 2 PH detection sensor, bidirectional valve, controller, automatic check valve, additionally, dilute acid supply, acidic water supply, basic water supply, and pretreatment according to water quality, application, sterilization Cl ion removal Various filters can be added.

Hereinafter, the spirit and process of the present invention will be described in more detail with reference to each step according to the present invention.

In the cationic resin treatment step, raw water, ie, raw water, is contacted and reacted with a cationic resin filter to convert unnecessary cations into H ⁺ ions, thereby removing harmful cations dissolved in water and converting water into strong acid. Perform the function.

At this time, the cation exchange resin is preferably made of a strongly acidic H ⁺ type to generate H ⁺ ions for strong acidification of water.

In addition, the anion number treatment step converts and generates unnecessary anions remaining in the water after the cationic resin treatment step into OH ^- ions or Cl ^- ions to remove the harmful anions dissolved in the water, and at the same time neutral to weak acidity It is in charge of the transition.

Here, the anion exchange resin is OH ^- and to switch the type made up of, a strong acid cation resin am torch water while treatment with neutral to weakly ^acidic-type or Cl ^- ions or Cl ^- OH to weakly basic to generate ions. In particular, when the anion exchange resin is Cl ^- type, an additional carbon filter for removing Cl ^- is required.

Water that has undergone anion exchange resin should be kept acidic. That is, the water retains a large amount of H ⁺ ions so that the ions react with minerals in the reactor such that the metals such as metals are oxidized to cations and H ions are replaced with H ₂ to generate beneficial cations through the minerals. to be.

Water passing through the anion exchange resin has a problem that when the anion exchange resin is Cl ^- type, the acidity of the water acidified through the cation exchange resin remains as it is, but the anion removal rate is lowered. ^- If you use a type anion removal rate is higher, but there is a problem that if water is PH neutral or close to neutral can follow.

Therefore, the water passed through the anion exchange resin is subjected to the first PH control step primarily for the acidification of water.

The first PH sensing and adjusting step is performed when the first PH sensing sensor provided in the discharge portion of the anion exchange resin measures the pH of the water that has passed through the anion exchange resin, and thus does not meet the predetermined PH condition. In the case of having a weak acidity, neutral to basic properties of the acid rather than the degree of acidity, the pH control treatment of water is primarily performed for acidification of water.

Specifically, the first PH control step, the process of supplying a portion of the water passed through the cation exchange resin through the bi-directional valve, the process of replacing the anion of the water with an organic acid in the anion exchange resin, a dilute acid of 0.01 ~ 0.1 M concentration Including the process of any one of the process, the pH of the water passed through the positive / negative ion exchange resin is treated with acid.

1) Process of supplying a part of the water passed through the cation exchange resin

This process can be especially useful when the anions in the raw water are relatively small and have the purpose of being used as agricultural water.

If the pH of the water measured by the first PH sensor is not PH having a predetermined acidic property, the bidirectional valve installed around the discharge port of the cation exchange resin is treated to open. There are two branch pipes formed around the discharge port of the cation exchange resin, one of which is directed toward the anion exchange resin, and the other is branched again to avoid the entry into the anion exchange resin and immediately exchange the anion. It is divided into a direction toward the discharge port of the resin, and toward the acid water supply to be described later, the bidirectional valve is to serve to control the flow of water in the two-way pipeline. It can be seen that this bidirectional valve is used for connection of some configurations with reference to FIG. 2.

In other words, when the two-way valve is opened to adjust the pH of the water introduced into the reactor, that is, to pursue acidification, the water flows toward the anion exchange resin and immediately flows around the outlet of the anion exchange resin (neutralization and basicity). The acidification of the water can be pursued around the outlet of the anion exchange resin by mixing water (strongly acidification) that has passed only the cation exchange resin.

2) Process of substituting anion of water with organic acid in anion exchange resin

Substitution of the anion of the water to be treated in the anion exchange resin with organic acid (vitamin C, malic acid) ensures the state of maintaining the acidity of the water without generating OH ^- similarly to when the anion exchange resin is Cl ^- type. At the same time, it can not only remove more kinds of anions, but also protect the ionic resin from contamination of organic matter.

That is, the organic acid that can be used in the anion exchange resin is to use a relatively small size and harmless vitamin-C or malic acid.

The anion substitution method in the anion exchange resin can easily substitute harmful anions of water by passing a solution of an organic acid or a salt thereof in an OH ^- type anion exchange resin having a weight ratio of 1 to 10 to the weight of the total anion exchange resin.

This method may provide the advantage that an organic acid is fed to produce a functional product that promotes the absorption of minerals formed in the reactor or may be used with the method of 1) above.

3) Process of adding dilute acid with 0.01 ~ 0.1 M concentration

This method is provided based on a systemic environment in which a dilute acid feeder is separately provided in the apparatus according to the present invention and connected to it around the anion exchange resin outlet.

The dilute acid feeder is provided with a supply means capable of preliminarily storing dilute acids (edible organic acids such as HCl to citric acid and chitosan) in a concentration of 0.01 to 0.1 M, and the pH of the water detected by the first PH sensor and the preset acidic PH. Depending on the difference, supply a small amount of dilute acid around the discharge port of the anion exchange resin by a very small amount. For this purpose, the diluent feeder can be provided with a check valve.

This method can also provide the ability to produce functional water that promotes the absorption of minerals.

The above-mentioned methods 1) to 3) may be optionally provided, or may be provided in combination of two to three as necessary.

In the reactor, H ⁺ ions contained in a large amount of acidic water are reduced to H ₂ through a reaction process with metals, thereby producing metal cations, namely, minerals such as potassium, magnesium, and calcium. Thereafter, the reaction is performed with minerals or poorly soluble salts to produce secondary minerals. The reactor may be equipped with a variety of pretreatment filters for this mineral generation process.

Through the reduction of H ⁺ ions into H ₂ and the formation of metal cations, ORP (redox potential) is drastically reduced, that is, a value of -125 mV to -60 mV is secured and ultimately the water is converted into reduced water. Becomes

The first PH adjusting step according to the present invention focuses on making the water undergoing anion exchange resin have acidic properties for reaction with mineral salts in the reactor, while the second PH adjusting step according to the present invention is used. Depending on the intended use of the reducing water, the pH of the water is detected if it does not reach the specific PH by detecting whether it is an acid / base specific pH that is preset according to the purpose so that the reducing water having weak acidity or weak basicity can be finally derived. It is in charge of secondary control.

In other words, the second PH adjusting step is a process of inputting the PH adjusting water when the PH of the water around the outlet of the reactor is measured by the second PH sensor and the measured pH of the water does not reach or exceeds the predetermined level PH. Go through

Specifically, referring to Figure 2, the pH control water supply is provided independently in the reactor, it can be seen that the pH control water supply is divided into an acidic water supply and a basic water supply, respectively.

The acidic water or basic water provided in the acidic water / basic water supply machine may be supplied with the acidic water or the basic water generated from the cation exchange resin or the anion exchange resin, respectively, and for this purpose, the cation exchange resin or the anion exchange resin It is possible to form a supply pipe to each of the acidic water / basic water supply in order to receive a certain amount of acidic water / basic water.

At this time, the supply pipe is provided with an automatic check valve to adjust the amount to be supplied to the reactor in fine units, thereby performing a function that can achieve a final pH control more precisely.

More specifically, the controller includes a controller capable of controlling the opening and closing degree of the automatic check valve, wherein the controller analyzes the numerical difference between the measured PH and the reference PH measured by the second PH control sensor to determine the supply amount of the acidic or basic water. Then, it serves as a control means for adjusting the opening and closing degree of the automatic check valve in accordance with the determined amount.

The bidirectional check valve is connected to the discharge tube of the acidic / basic water supply around the discharge port of the reactor, and if the pH measured by the second PH sensor is different from the intended pH, the bidirectional check valve is connected to the discharge port of the acidic water supply or the basic water supply. Opening the automatic check valve provided serves to mix with the water discharged from the reactor in the vicinity of the reactor outlet.

In more detail, the second PH adjustment step, the second PH sensor installed around the discharge port of the reactor detects the PH of the water discharged from the reactor is not a specific PH, that is, set the specific PH to 8.5 if the discharged If the pH of the water is 6, open the automatic check valve of the basic water supply in the bidirectional valve to supply basic water around the discharge port of the reactor (before the installation position of the second PH sensor), so that the water first discharged from the reactor is basic. If the pH of the discharged water is 9, open the discharge tube valve of the acidic water supply in the bi-directional valve to supply the acidic water around the discharge port of the reactor to match the initial discharged water from the reactor.

At this time, the second PH sensor is located behind the discharge pipe supplied from the acidic / basic water supply to objectively measure the PH of the mixed water of the water supplied from the acidic / basic water supply and the water discharged from the discharge port of the reactor. Measure with

In addition, the water discharged from the reactor again meets the bi-directional valve, in the case where the pH measured by the second PH sensor is different from the reference PH (target PH), in particular, if the pH is more acidic than the reference PH When the water is supplied to the acidic water supply and has more basic properties than the reference PH serves to supply the water to the basic water supply.

That is, water different from the reference PH is not suitable for the purpose, but it is wasteful to contain a large amount of mineral components through a reactor for disposal, and a part of the water generated from the cation exchange resin or the anion exchange resin to the acidic / basic water feeder is discarded. In order to supply, but more smoothly and sufficiently feed back the acidic / basic water to adjust the pH of the water discharged from the reactor in accordance with the reference PH in more real time.

Through this process, it is possible to finally obtain reduced water that meets the reference PH.
